炭素同素体が高分子材料の熱分解に与える影響. (Japanese)

In this paper, the effects of various carbon allotropes on the pyrolysis of two polymers, polystyrene (PS) and polyethylene (PE), was measured by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and the results were compared with the results for samples without carbon allotropes. For both PS and PE, as the mass of added multi-walled carbon nanotubes (MWCNT) increased, the change in the composition of pyrolysis products became more conspicuous. Furthermore, the compositional changes of pyrolyzates from PS and PE showed the same tendency for all investigated carbon allotropes (MWCNT, single-walled carbon nanotubes, graphene nanoplatelets and carbon black).

報では， 炭素同素体が高分子材料の熱分解に 与える影響の解明の一助とすべく， ポリスチレン(PS) およ びポリエチレン（PE) に対して種々の炭素同素体共存下にて 熱分解-ガスクロマトグラフィー/質量分析法（Py-GC/MS) による測定を行った. また， それらの熱分解物に着目し て通常の熱分解との比較を行った.多層カーボンナノ チューブ(MWCNT) 共存下において， P S およびP E ともに MWCNTの質量の増加に伴って， 熱分解物の組成変化が顕 著になることが確認された. また， MWCNT, 単層カーボ ンナノチューブ， グラフエンナノプレートレットおよび松 煙共存下での試料の熱分解物の組成変化を比較すると， すべてにおいて同様の傾向がみられた. は， PSおよびPEに共通して末端二重結合を有する熱分解物のさらなる分解が確認された.
